After the completion of Sanxia Production, most of the summer harvest farm machinery counties will be put into the upcoming autumn harvest production. Many agricultural machine users have neglected the maintenance and maintenance of their machines during the autumn agricultural machinery operation. Repair and maintenance of the machine should pay attention to the following points: First of all, it is necessary to promptly eliminate the weeds, dirt, and other deposits on the outside of the harvesting machine to eliminate the wheat straw, wheat bran, wheat grain, and soil that are present inside the machine. All kinds of shells, thin iron parts and other rust-prone parts should be painted or fully painted and maintained. The appearance is free of rust spots. For the parts of the corn harvester that must be lubricated, lubrication oil should be added in time to reduce friction, reduce the consumption of harvester power, improve the reliability of the harvester, and extend the life of the harvester. Lubricating grease is added to each lubrication point; each exposed chain, sprocket, cutting table knife row, coulter, etc. shall be separately immersed in the oil pan, or coated with oil, or brushed and tarred; remove the chain, With the diesel oil brushed clean, dirt, and then soaked in the oil, this can extend the life of the chain. Second, the harvester must check the tightness of the V-belt prior to operation, and too loose or too tight can affect the life of the harvester. Too loose a triangular belt will cause slippage and reduce work efficiency; over tightening of the triangle belt will increase bearing wear, increase power consumption, and may cause the shaft to be bent. In addition, the harvester must check the tightness of the sprocket before the operation, too tight and easy to wear, too loose chain to jump big, and even jumping off the teeth and the chain off. Once problems are found in agricultural machinery, it is necessary to promptly replace the defective parts, repair the fractures of the support plates and support frames, and ensure the technical integrity of the mechanical framework. The external equipment rust blocks should be stored after the entire vehicle is painted. To control the maintenance requirements, add lubricating grease to the agricultural implements being operated, tighten loose bolts, check for missing parts, and replace missing parts promptly. After the maintenance is completed, ensure that each locomotive meets the requirements of “Four nets, three leaks, and one intactâ€, that is, oil net, water net, net net, locomotive net; no oil leakage, no water leakage, no air leakage; the technical state is intact Can be stored. LED traffic lights are an indispensable tool in urban traffic and an important guarantee for urban traffic order. This example is to implement a common traffic signal light function at an intersection. Readers can realize a more complete LED Traffic Light by learning this traffic light controller. For example, real-time configuration of the time of various traffic lights, manual control of the status of each light, etc. Red Green Countdown Timer,Traffic Light Countdown,Traffic Signal Countdown Timer,Traffic Light Timers Shenzhen Wide Way Optoelectronics Co., Ltd. , https://www.wdmtrafficlight.com
Traffic at an intersection is generally divided into two directions, each direction has three types of red, green and yellow lights, and each direction also has a left turn light, so each direction has 4 lights.
This LED traffic light is also designed with a countdown traffic light display function for the status of each light. You can set an initial value for each light state, and after the light state changes, it starts to count down according to this initial value. After the countdown is reset to zero, the state of the light will change to the next state.
It is worth noting that the state of the traffic signal lights in the two directions is related. In other words, the state of the lights in each direction affects the state of the lights in the other direction, so that the traffic flow in the two directions can be coordinated. If the lights in each direction change independently, then the traffic lights have no meaning.
